Recognize the names as well as the numbers
The family includes B1 thiamin, B2 riboflavin, B3 niacin, B5 pantothenic acid, B6, B7 biotin, B9 folate and B12. Missing numbers in that familiar sequence are not instructions to add extra unidentified vitamins. [1]
These nutrients support different normal processes, including use of energy from food and blood-cell formation. They cannot all be treated as interchangeable versions of one vitamin. [1]
Read each nutrient amount separately
A B-complex product combines ingredients, while an individual-vitamin product targets a narrower formula. The group name does not tell you how much of each nutrient is present. [1]
Compare the listed amounts with the actual nutritional or clinical purpose. A need for one vitamin does not, by itself, establish a need for high amounts of all eight. [1]
A family label is not a dose
Imagine two products both say B complex. Their B6 and B12 amounts can differ, so the front label is insufficient for an exposure comparison.

| Eight nutrients | Distinct identities |
| B complex | Group or product description |
| Amounts | Read nutrient by nutrient |
